postulates of the kinetic molecular theory of gases

All gases are made up of large number of minute particles called molecules. Large distances separate the molecules so that the actual volume of the molecules is negligible as compared to the total volume of the gas. The molecules are in a state of constant rapid motion in all dire..

In order to explain the observed behaviour of gases, a model was proposed based on the molecular and kinetic concept of gas molecules. This model takes into account the particulate nature of matter and the constant movement of particl..

The word 'Kinetic' means due to motion. The Kinetic Theory of Gases is based on the idea that gases consist of atoms and molecules moving ceaselessly and randomly with all possible velocities in all directions. Each of these gas particles has certai..

All the molecules of a gas are identical with respect to their shape and mass. The molecules of different gases are differen..

>Matter consists of molecules. These are the smallest particles, which are capable of free existence and retain all the chemical properties of the parent substance. The molecules are always in a state of random continuous motion. The molecules exert forces on one another. These forces depend upon i..

Properties of Gases in Terms of Molecular Motion - Gases, as well as mixture of gases, behave as seen above, with regard to changes in temperature, pressure or both. The following assumptions can be made on the basis of the kinetic theory ..

Heat and Motion (Kinetic Theory of Heat) - Under normal conditions matter exists in three forms: solid liquid gas Matter is made up of atoms and molecules. These atoms in molecules are in a state of continuous motion. For example, molecules and atoms of a solid can have only vib..

or The units of E k depend upon the units of R. Hence the following point holds true: The assumption of kinetic theory that the average kinetic energy or molecular velocity of any gas is directly proportional to its absolute temperature. K.E a u 2 ..
